Two Northland beekeepers have offered rewards totalling $8000 for tip-offs leading to the conviction of saboteurs and thieves attacking their hives.
John Whitehead, of Kerikeri, is offering $5000 for information on the poisoning of about 90 hives on four sites along Paponga Rd, near Broadwood.
And Lindsay Guest, of Kohukohu, has $3000 to reward someone who will tell him who stole 17 hives and tipped seven others over at the Skyline Hill on the West Coast Rd.
Police are investigating both incidents in an industry that is becoming increasingly competitive as prices for top-quality manuka honey rise to a massive $400-plus a kilogram.
Mr Whitehead said the poisoning of nearly four million bees in his hives was an inhumane act. "The bees were slaughtered and left as a stinking, rotting mess," he said.
